A composition according to any of the preceding claims, obtained and/or preferably wherein said alkaline agent is allowed to evaporate after application of said composition to freshly harvested crops. A composition according to any preceding claim, further comprising one or more spacing agents,
The composition, wherein said spacing agent is a polyol, such as a polyol selected from the group of glycerol, sorbitol, propylene glycol, polyethylene glycol or mixtures thereof, preferably glycerol. A composition according to any preceding claim, further comprising lecithin and/or ammonium phosphatides and/or antifoaming agents . A composition according to any of the preceding claims, which is free of organic solvents or contains organic solvents at a percentage of less than 5 w/v% of said emulsion. glycerol monostearate in an amount of 1-10% w/v of the emulsion; oleic acid as fatty acid in an amount of 1-5% w/v of the emulsion; and 0.1-10% w/v of the emulsion. of the alkaline agent, the balance being water . glycerol monostearate in an amount of 1-10% w/v of the emulsion; oleic acid as fatty acid in an amount of 1-5% w/v of the emulsion; and 0.1-10% w/v of the emulsion. 10. A composition according to claim 9 , comprising ammonia as the alkaline agent and the remainder being water. glycerol monostearate in an amount of 1-10 w/v % of said emulsion; oleic acid as fatty acid in an amount of 1-5 w/v % of said emulsion; 11. The composition of claim 10 , comprising glycerol as a pacing agent; and ammonia as an alkaline agent in an amount of 0.1-10% w/v of said emulsion, the balance being water. 12. A method according to any of claims 1-11, comprising ammonia in an amount of 1-10 w/v% of said emulsion, or ammonia in combination with NaOH or KOH in a total amount of 1-10 w/v% of said emulsion. composition. After harvesting, freshly harvested produce, preferably selected from the group of fruits, vegetables, flower bulbs, potted plants and cut flowers, is coated with a composition according to any of claims 1-12 . A method of coating fresh harvest comprising: Use of a composition according to any one of claims 1 to 12 for the preparation of post-harvest fruits or vegetables with long shelf life and slow weight loss. Use of a composition according to any one of claims 1 to 12 for the preparation of post-harvest cut flowers or potted plants with long shelf life.
